Thanks Les and congratulations on the successful observation. I forgot to mention my observations were made with a 4.5mm eyepiece (511x) with a TV coma corrector(1.15x). I did try with a 3.5mm EP(657x) which was still quite useable but it meant nudging the scope more frequently to keep the field centred. To make sure I was not misidentifying the quasar with another field star I made note of the pattern of two overlapping triangles with the quasar forming the apex of an equilateral triangle and a 16.75 mag star forming the apex of an Isosceles triangle. That way I was able to confirm the quasars location. What also helped in my situation was memorising the finder field and not having to look at a chart and stuffing up my dark adaption. Knowing I can get down to at least the early 17th magnitude, my next target will be a quasar in Eridanus (HE 0435-1223) not far from Rigel, which I've already scoped the field out for last week.
